hmmm yes the probe is inside the tub, as i thought it was the egg-tub that needed to be heated to 90ish?

it's on a proportional thermostat (Herpstat) so it shouldn't really be fluctuating too much.

the high/low reads 88.3 - 89.2

I truly believe its due ot having the thermostat probe inside the tub.

Its tough messing with eggs when their already in the incubator. Id say take the thermostat probe OUT and set it on the shelf in incubator next to the tub. Set thermostat to 88.5. Wipe the condensation out and see.


I have a full size upright freezer that holds 28 6qt tubs. I have the probe outside hanging in the middle of the bottom shelf. Herpstat is set at 88.1 and inside the tubs i get 87.5 and top is 88.3.

Also a small computer fan about 80-90mm in size to circulate the air might help a ton as well

you will notice at bottom my herpstat probe is hanging in middle

and yeah, i do hate messing with them. they've already dealt with their tubs being wiped out a few times, and also a move from the stupid hovabator to the cooler.

how do you measure your temps, do you have multiple thermometers in the incubator? i just have the thermometer probe and tstat probe tied together. should i put the thermometer probe inside the egg tub, or just leave it with the tstat?

sorry for all the questions, and thanks so much for all of your help!

I dont measure my egg tubs. I keep a probe at the top and bottom along with herpstat probe. When i check eggs every 2 weeks ill zap them with temp gun and always 87.0-88.3 in the egg tubs.

Your best off putting the t-stat probe and thermometer one as well outside the tub next to it. Wipe off the condensation, and check back in morning/after noon. Should fix the problem.

alright thanks, i'll let you know how it goes in the morning!

grrrrrrr the gosh-darn humidity was back this morning!! not as bad, mind you, but i also didn't leave it 24 hours like last time.

i wiped again, and placed paper towels under the lid.

maybe it's just because it goes from like 28 during the day down to 9 or 10 degrees at night. who knows.

we're looking for an old broken wine-cooler for next year, but this will have to suffice right now.

Whats the Room temps the incubator is in. That will play a roll as well when you keep opening and closing lid.

Best kept it in warmest room

75.6 - 82.9, but i don't think the max/min have been reset in awhile, i don't see how it could have gotten down to 75 recently, it's been pretty hot out
